SPINDLE-FORGIN G MACHINE.

SPECIFICATION forming part of Letters Patent No. 791,204, dated May 30,1905. Application filed July 5, 1902. Serial 1T0. 114,327.

1'0 all whom, it may concern.-

Be it known that we, HENRY A. OWEN and CHARLES T. BURLIN, citizens ofthe United States,-residing at Whitinsville, in the county of Worcesterand State of Massachusetts, have invented a new and useful Improvementin Spindle-Forging Machines, of which the following is a specification.

This invention has reference to a machine for heating the blanks forspinning-machine spindles.

The object of the invention is to automatically convey the blanks to theheating-fur-' nace, heat the blanks, and convey the heated blanks to aconvenient point to be forged.

The invention consists in the peculiar and novel construction and thecombination of the cooperating parts whereby the handling and theheating of the blanks are facilitated, as

. will be more fully set forth hereinafter.

In carrying out the invention we have provided a suitable magazine orreceptacle in which any desired spindle blanks may be placed. Anautomatically operating selector delivers at predetermined intervals ablank from the magazine into a conveyer, by which it is delivered to acarrier, which carries the blank through the heater. The heated blank isnow dropped into a conveyer, by which'it is carried to a convenientpoint to be forged or otherwise formed into a spindle.

Figure 1 is a plan view of our improved machine, shown partly insection. Fig. 2 is a side elevation of the same, shown partly insection. Fig. 3 is a vertical sectional view, on an enlarged scale,showing the carrier and heater in relation to the conveyer by which theheated blanks are supplied to the forger. Fig. 4 is a top view, partlyin section, showing the relation of the selector with the magazine andthe conveyer. Fig. 5 is an end View of the selector, taken at rightangle to Fig. 4:, showing its relation with the magazine. Fig. 6 is adetail view, partly in'se'ction, showing the blank-holder on the end ofthe first conveyer in connection with the carrier. Fig. 7 is a sideview, partly in section, of the delivery end of the conveyer of heatedblanks,

showing the counterweighted stop. Fig. 8 is a vertical sectional view,on an enlarged scale, of a furnace which has no side opening, the blanksbeing lifted up into the heater, the means for lifting the blanks, andthe relation of the several parts. Fig. 9 is a plan view of the carrierand the heater, the heater being shown in section.

Similar marksof reference indicate corresponding parts in all thefigures.

In the drawings, A A indicate the frames forming the support of themachine, and a the magazine, consisting, as shown in the drawings, ofthe plate a and the guide-flanges a m The magazine is placed in aninclined posi tion, so that the blanks b when placed on the plate a willroll or slide down on the plate, guided by the flanges a a until theforemost one of the blanks Z) bears against the worm b on the peripheralsurface of the worm-disk b rotatably mounted on the shaft 6 At eachrotation of the worm-disk b the foremost one of the blanks inthe-magazine moves onto the worm-disk and, carried endwise by the worm,

drops into the conveyer-chute c, the bottom of which has the incline 0',which curves and terminates in the vertical end portion 0 Each blank asit is dropped slides downthe conveyer 0 and assumes the verticalposition as it enters the end portion 0 which has a vertical openingclosed by the hinged gate 0 held in the closed position by the spring a.

The blank 6 is supported on the carrier 0?, which is perforated by aseries of holes 03. The carrier consists of a wheel the ,hub of which issecured to the shaft 0Z through which rotary motion is imparted to thecarrier. The rim of the carrier is perforated at intervals with theholes CZ, into which the blanks b fit with a loose sliding fit.

When a hole (2 of the carrier registers with the blank t in'the end ofthe conveyer 0 ,'the blank drops into the hole d and would drop throughthe same, but is supported on' the stationery plate d which extendsfromytli'e end of the conveyer c to the point of discharge under the rimof the carrier. The blank which has entered the hole d of the carrier ismoved out of the end 0 by the carrier. The spring-pressed gate opens bythe force exerted by the carrier on the blank and is closed by thespring 0 for the reception of the next blank released by the worm.

The carrier d is rotatably mounted below the heating-chamber e, linedwith the refractory material a. In the preferred form theheating-chamber e is supported on the plate d and is provided at one endwith the verti cal slot in the wall and the segmental slot 6 in thebottom, through which the spindleblanks are carried into theheating-chamber. The heating-chamber may be heated in any suitablemanner, preferably by means of the gas or oil burner 6 The blanks aresubjected to the heat for the time necessary to prepare them forforging. Near the end of the segmental slot 0 in the bottom of theheating-chamber the plate (Z has the opening all, through which thespindleblank 6 passes when the hole cl, supporting the blank, registerswith the opening. The conveyer d receives the heated blank and guidesthe same to the end cZ of the conveyer. On this end (Z thecounterweighted stop-lever (Z is pivotally connected and serves toarrest the descent of the heated blank, so that the forger mayconveniently grasp the blank.

As shown in Figs. 8 and 9, a portion of the stationary plate (Z isplaced sufficiently below the carrier, as at 0 to allow the tops of theblanks to pass under the bottom of the heater, the plate graduallyrising, as at 0, until the blanks have been lifted up into the furnaceand the flat surface of the plate (Z is reached, as shown at 0 theblanks being moved along by the carrier (Z until the opening d isreached, through which the blanks I) drop into the conveyor d Themachine may be operated by any prime motor conveying power to thevarious parts to operate at the relative speed required. In thepreferred form, as shown in the drawings, the shaft f is provided withthe pulleys f. One of these is a loose and the other a tight pulley. Thepinion f on the shaft f gears with thegear f on the counter-shaft f thesprocket-wheelf on which is connected by an endless chain f 7 with thesprocket-wheel f on the shaft Z1 by which the worm-disk b is rotated.The worm f on the countershaft fengages with the worm-gear f, secured tothe shaft d of the carrier cl.

WVe do not wish to confine ourselves to the exact construction of thedriving mechanism or the operative parts, as these may be modifiedwithout materially affecting the result.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. In a machine of the nature herein described,the combination with the horizontally-rotatable carrier, holes in thecarrier for the reception of the blanks, and a plate extending under apart of the carrier, of a heating-chamber having a slot in one of thevertical walls and a slot in the bottom for the passage of theblanksinto and through the chamber, and means for rotating the carrier,as described.

2. In a spindle-forging machine, the combination of the followinginstrumentalities: a magazine for the reception of the spindleblanks, aselector for releasing one blank after the other at predeterminateintervals, a rotatable carrier, perforations in the carrier for thereception of the spindle-blanks, means for inserting the blanks into theholes of the carrier, means for supporting the spindleblanks in thecarrier, means for rotating the carrier, a heating-chamber having theinclosing walls covered with refractory material, means for dischargingthe heated blanks, and means for heating the chamber, as described.

3. In a spindle-forging machine, in combination, a heating-chamberhaving openings for the passage of the blanks through the same, a burnerfor heating the chamber, a revoluble blank-carrier, means for supportingthe blanks terminating at a point within the heating-chamber for thedischarge of the heated blanks, a conveyor, and a counterweighted stopat the delivery end of the conveyer, as described.

4. In a machine of the nature herein described, the combination of aheating-chamher, a carrier for the reception of the blanks, a plateformed to lift the blanks into the heating-chamber upon the rotation ofthe carrier, and means for rotating the carrier, and means forsupporting the blanks terminating at a point within the heating-chamber,as described.

5. In a machine of the nature herein described, the combination with theheatingchamber 0 provided with the slot 0 in the wall and the slot 0 inthe bottom of the heatingchamber, and the plate (Z of the carrier (Zrotatably supported on the plate d, the holes d in the rim of thecarrier, the opening in the plate (Z and means for rotating the carrier,whereby the blanks may be carried into the heating chamber and theheated blanks discharged, as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
